OpenRC F1 250% scaled

thingiverse

Here is the rewritten text: We took Daniel's original OpenRC F1 car and scaled it up. We made it bigger, to be precise, scaling it to 250% of its original size. That means this project is over 1m long and weighs about 8.5kg in total. To make it work on the larger size, we modified all the original files to accept larger bearings and bolts. To allow remote control of this beast, we custom designed a gearbox with a large reduction ratio and redesigned part of the steering arrangement to combine it with a massive steering servo. We used the Turnigy DMS-30 Steering Servo, which we hooked up straight to the battery to provide enough steering power. More details about the build and internal mechanics will be revealed in the coming weeks, but with these files, you can already start building your own 1 meter long OpenRC F1 car remix. We used colorFabb copolyster filament for all parts, each produced in the specific filament that matches with the part. The materials used include XT-CF20 for chassis parts, colorFabb_XT for general technical parts, colorFabb_HT for high-strength technical parts, nGen for bodywork, and nGen_FLEX for tires. We needed a big printer to print the body and chassis parts, so we used the Stacker S4 with its XY build volume. Some smaller parts were printed on various other printers, mostly Ultimakers. The print settings include a resolution of 0.10-0.2mm and infill levels of 7%-100%. The notes say that print resolution and infill levels are based on the specific requirements of each part. Chassis parts require 100% infill, while body parts need only a small percentage to support the structure. Some parts will require support to be printed properly, but most should print support-free thanks to the awesome original design by Barspin! Post-printing, use Daniel's original work as a general guide. He has a lot of documentation about his OpenRC projects and how to build the F1 car. Take a look at his YouTube channel for example, especially his Build With Me - F1 series. Combined with the original assembly drawings, you should be able to build most of the car. The bill of materials includes M6 countersunk bolts and M6 Nyloc nuts. Make sure you have plenty M6 available between lengths of 25-40mm and be prepared to cut some to size. Customized parts also use M3 brass heat set inserts for the servo mount and gearbox, as well as grubscrews holding it into place on the shafts. Two of the 688 bearings are inside the motor gear, allowing the shaft of the final reduction stage to support the motor gear. The other two 688's support the other end of the same shaft as it moves outside of the body to the final gearing. Every project needs LEDs, especially a race car! We reproduced the same lights as an actual F1 car has by mounting 3x4 LEDs in the rear wing mount. Combined with a small power converter being powered straight from the battery, this adds a simple but really cool finishing touch to the project. We took Daniel's original .step files as a basis for scaling this model. He built up this entire project from scratch using Autodesk Fusion 360 CAD software. We continued the work in SolidWorks 2016 to scale up and modify the parts where needed. The gearbox has been designed from scratch in SolidWorks. The OpenRC project was started by Daniel Norée in 2013, and it has produced some amazing 3D printed projects over the years. With the F1 car as the newest addition to the OpenRC fleet, colorFabb decided once more to tackle an OpenRC build, but this time a bit bigger. We have been in contact with Daniel throughout this build and can't thank him enough for all the work he has done on this and many other 3D printable models. We can't wait to see what he comes up with next!
